Hi Armando. Great to have you join WPSE. I realize this is your first answer, but wanted to make you aware of a matter of protocol here. Link only answers are considered poor quality answers. If the external link is removed, your answer becomes benign. Please update your answer with more details of why/how this helped you. It's also good to post code snippets or quotes from the original article here with a citation to that article. Thanks!
